The global waste volume is projected to surpass 11 million tons per day by 2100. Agriculture, a major consumer of land and water resources, contributes to food waste generation. Solutions for valorizing food waste must be tailored to the specific needs of different parts of the world. Communities globally are striving to attain the goal of "zero waste,’ a core concept that revolves around the implementation of technologies, regulations, and policies geared towards minimizing waste generation. The emphasis is on encouraging the reuse of all products, while minimizing use of landfills or incinerators.  Ionizing technologies, are poised to emerge as the pivotal platform for achieving financial and technological feasibility in the pursuit of zero waste. Isotope-based technologies like Co-60 and Cs -137 will face technological and financial challenges in the future. Accelerator technologies, especially eBeam, are anticipated to take center stage. A notable characteristic of this technology is its cost-effectiveness, particularly as it scales. Currently, there are diverse options in terms of energy, ranging from low to medium to high energy, readily available in the commercial market. However, there is an urgent demand for multiple commercial vendors to provide eBeam equipment and its components.  A critical requirement exists for accelerators encompassing various beam energies and powers to cater to diverse applications.  In addition to fostering coordination, collaboration, and funding for the advancement of this technology, prioritizing workforce training, and engaging in stakeholder outreach and education activities should be a paramount and concentrated effort.
